We did Coral World and Coki beach trip (thru cheapcruises.com) in the morning. Both of them are right next to each other. So if you take any one of them, you can see the other. Coral world is a big disappointment. After watching Monterey Bay aquarium, Coral world looks like an infant.Coki beach is very crowded, but crystal clear waters. After that, we went to Megan's beach. A wonderful beach and a must do for any one. It is so wonderful, we just relaxed there for 4 hrs or so. There are taxis which take you to Megan's bay beach from Port for $8 per head.
